STANCHION.

Application led March 30, 1923. Serial No. 628,860.

To all whom t ma@ concern:

Be it known that we, BRUNO Evfnno ROTH- IG and ERNEST ALBERT ARNOLD, citizens of the United States, residing at Eau Claire, in the county of Eau Claire and State of 1Wisconsin, have invented certain new and useful improvements in Stanchions, of which the following is a specification.

This invention relates to Stanchions, and more particularly to locking mechanism therefor.

An object of the invention is the provision of a stanchion having a pair of guides carried b the movable member arranged on each side of the stationary member.

A further object is to provide a Self-contained stanchion in which there are no parts projecting beyond the vertical arms even when the device is in open position.

A further object is the provision of an improved stanchion of simple construction.

In the accompanying drawings, we have shown one embodiment of the invention. In this showing:

Figure 1 is a perspective View of the stanchion,

Figure 2 is a plan view,

Figure 3 is a vertical sectional View on line 3-3 of Figure 2.

Figure 4 is a transverse sectional view on line 4.--4 of Figure 3, and, n

Figure 5 is a detail view of the locking member.

Referring to the drawings, the reference numeral 1 designates generally the stationary member of the stanchion and 2 the movable member. As shown, the stanchion is substantially rectangular when in closed position. rlhe stationary member is formed of channel iron, consisting of a base 3 and parallel side walls 4. The lower end of this channel iron is bent to form a base 5 and the upper end is extended at right angles to the vertical portion to form a top 6. A reenforcing member 7 may be secured to the vertical portion of the stationary member, if desired. `The lower end of the movable member is arranged at right angles to the body portion as indicated at 8, and is connected to the movable member by a suitable hinge 9. The movable member is likewise formed of channel iron, consisting of a base 10 and parallel side walls 11. The movable member may be rovided with a reenforcing member 12, similar to the reenforcing member 7. The upper end of the base of the movable member is extended inwardly Yto form a lip 13. When the stanchion is iu closed position, the ltop 6 of the stationary7 member is received beneath this lip. locking member 14 is pivotally mounted on a pin '15, arranged in the side walls of the top of the stationary member. This locking'member` is provided with a tooth 16, adapted to engage the movable member, as shown. A pin 17 is mounted in the base of the stationary member and extends through a slot 18 in the locking member. Y A spring 19 is arranged on this pin and bears against the locking member to normally retain it in closed position. A reenforcing member 2O is arranged around the end of the stationary member and the upper ends of this member areV offset, as at 21, to engage the top of the locking member when it is released and limit its upward movement. A finger grip 22 is formed on the top of the locking member to facilitate its release. A pair of guide members 23 are se cured to the upper end of the movable member and extend on opposite ysides of the stationary member (see Figures 1 and 2). The ends of these guides are offset, as at 24, to engage the member 2O to limit the outward movement of the movable member.

The stanchion may be supported in any suitable manner. As shown, screw eyes 25 are arranged in the top and bottom and are are adapted to receive chains 26 to support the stanchion in the usual manner.

The operation of the -device will be apparent from the foregoing description. The locking member is released by lifting it to the dotted line position shown in Figure 3 of the drawings, and the movable member may then be readily moved to the dotted line position shown in Figure 1 of the drawings, the lip 13 being free to pass the tooth 16 when the locking member is raised. As the movable member is moved to open -position, the ends 24 engage the flanges 21 of the reenforcing member 20 to limit the movement and prevent the guides from passing beyond the stationary member. When the movable member is moved to closed position, the lip 13 rides over the inclined portion of the tooth 16, lifting the tooth against the tension of the spring 19. When the inner edge of the tooth is clear of the lip, the tension of the spring moves the tooth to closed position, as shown in Figure 3 of the drawings.

It is to be understood that the form of the invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be re sorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described our invention, We claim:

l. In a stanchion, a pair of substantially parallel members having their lower ends extended to form base portions, said base portions being hinged to each other, the upper end of one of said members being eX- tended substantially at right angles to the body to form a top, guides secured' to the upper end of the other member and arranged on each side of said top, the free end of said guides beingoffset, a. member embracing said top and receiving said guides, said member being adapted to be engaged by said offset ends to limit the movement of said members, and a locking member carried by one of said members and adapted to engage the other member.

2. In a device Gf the character described, a stanchion comprising a pair of substantially parallel members formed of angle iron` said members being extended tovform base portions, said Vbase portions ybeing hinged to each other, the upper end of one of said members being extended substantially at right angles to the body to form a top, guides secured to the upper end of the other member and arranged oneach side of said top, the free ends of said guide being offset, a member embracing said top and arrange-d on the outside of each of said guides.y said member being adapted to be engaged by said odset ends to limit the movement of said lirst mentioned members, and ar locking device pivotally mounted between'tliefside Walls of said top andradapted to engage the upper end of the otherA member.

In testimony whereof. We aiiiXAour signatures in presence of tivo witnesses. f
